Great product... read review before buying for radar detectors though.
I purchased this product with the intention of mounting it in the windshield of my Nissan Altima to hold my Escort Passport 8500 X50 Radar Detector. I received the product in a timely fashion. Just so you know, there is nothing on the mount part to hold on to a radar detector. You're going to need some Velcro or something to hold it in place. Placing it on top of the mount, I was concerned about the suction cup blocking the sensors on the front of the detector (the suction cup is HUGE). I went to the store and purchased some Velcro industrial strength (also available on Amazon). I stuck some on the bottom of the mounting piece and on top of the detector and let it set for at least 12 hours. Now I can just stick the detector to the bottom of the mount and have no worries since the Velcro is strong as well. A very stable setup! I would also add that I have it mounted upside-down vs. the way it is in the pictures. Anyway, as far as the product goes...

PROS- Very sturdy, HUGE suction cup that stays plastered to the windshield, even in the mid-summer Louisiana heat and humidity, doesn't look bad, doesn't have to be taken down to be able to use a sunshade

CONS- Even after you use the suction release switch and pull on the raised piece of the suction cup, you still need to pry it off of the windshield unless you want to run the risk of breaking it, no included way of mounting a radar detector and can only be mounted one way without obstructing the detector

It literally sucks
I put it on a glossy paint door, it sucked. I put it on the bathroom mirror, it sucked. I was afraid to pull hard, the mirror may fall from the wall. It's in my car now, has yet to fall off. I noticed there is a spring mechanism, appears to reduce the impact of heavy items attached. So even if there was a heavy jerk, the spring would reduce the force. I've noticed other suction cups on similar items have a smaller contact patch as well. Works great... my $.02

Useful Accessory
I purchased this product to mount an XM satellite radio antenna inside a company vehicle used by multiple drivers. This allows me to leave the anntena and it's wiring configured for easy re-installation whenever I use the vehicle. This product works as advertised for my application.

Very good!
Ordered this at the same time as ordering a Cobra XRS 9340. I'm VERY pleased with the design & function of this device. As i see it it's a must have since the original suction cups that come with most laser/radar warners are crap.

Great quality product
Very nice product, good for GPS mounting,radar detector,or satellite radio reciever. does what it says well,so I give it a 5.
